What are common causes of the "Cannot send session cookie" and "Cannot send session cache limiter" errors in PHP when starting a session?

The "Cannot send session cookie" and "Cannot send session cache limiter" errors in PHP typically occur when there is output sent to the browser before starting a session. To solve this issue, make sure that session_start() is called before any output is sent to the browser, such as HTML, whitespace, or PHP errors. 

<?php
// Start the session before any output is sent
session_start();

// Your PHP code here
?>
